Embodiment Construction

[0017] In order to make the technical solutions and beneficial effects of the present invention clearer, the implementation manners of the present invention will be further explained in detail below.

[0018] Such as figure 1 As shown, a noise reduction and temperature reduction device for a converter transformer includes a vertical partition 1 , a heat-absorbing partition 2 , and a top plate 3 .

[0019] The side of the heat-absorbing partition 2 facing away from the converter transformer is provided with cooling strips, and the cooling strips are perpendicular to the heat-absorbing partition 2 . In order to better realize heat absorption and heat dissipation, the heat absorption partition plate 2 is made of metal with better heat conduction effect. Simultaneously in order to guarantee equipment and life safety heat-absorbing dividing plate 2 is connected with the earth. The heat absorbing partition 2 has the function of heat conduction.

[0020] In order to increase the h...

Abstract

The invention discloses a noise reduction and temperature reduction device for a converter transformer. The device includes a vertical partition, a heat-absorbing partition and a top plate. The heat-absorbing partition is arranged around the converter transformer. The upper part of the heat shield. The invention has the beneficial effects of good sound insulation effect and high ventilation and heat dissipation efficiency.

Description

technical field [0001] The invention relates to the field of noise treatment of electrical equipment, and relates to a noise reduction and temperature reduction device for a converter transformer. Background technique [0002] Converter transformer (Converter Transformer) is a power transformer connected between the converter bridge and the AC system. The converter transformer is used to realize the connection between the converter bridge and the AC busbar, and to provide a three-phase commutation voltage with a neutral point not grounded for the converter bridge. The converter transformer and the converter bridge are the main body of the converter unit. [0003] The noise of the transformer is a kind of continuous noise generated by the vibration of the transformer body and the vibration of the cooling device. The magnitude of transformer noise is related to factors such as the capacity of the transformer, the material of the silicon steel sheet, and the magnetic flux den...
